Publication number: 20130004790Abstract: In the composite, an aluminum-plated steel sheet and a resin are securely and integrally joined together. Through chemical etching, the aluminum-plated steel sheet is caused to have a surface configuration, in which three-dimensional protrusions having shapes with a minor diameter of at least 0.3 ?m and a major diameter of at least 3 ?m are scattered over a plain part and a portion covered with shallow fine recesses with a diameter of 20 to 50 nm in a state of being distributed adjacent to each other on the plain part accounts for 30 to 50% of the surface area of the plain part. The surface of the three-dimensional protrusions is mainly ceramic containing silicon and the plain part is mainly ceramic containing aluminum. The resin is joined through injection molding with the aluminum-plated steel sheet having been inserted into a metallic mold.Type: ApplicationFiled: September 10, 2012Publication date: January 3, 2013Applicant: TAISEI PLAS CO., LTD.Inventors: Masanori NARITOMI, Naoki Andoh

Publication number: 20120321802Abstract: A method of forming a concrete wall having a substantially uniform exterior surface texture. The method includes the initial step of pouring concrete into a wall form. The concrete is poured from a first mixture and is allowed to cure. After the concrete is cured, the wall form is removed from the resultant concrete base structure. A roughened texture is then created on the base structure. A finishing mixture is then applied to the roughened texture. The finishing mixture may be created by separating the aggregate from a portion of the remaining first mixture. The finishing mixture creates a smooth texture on the exterior surfaces of the initially formed base structure.Type: ApplicationFiled: August 27, 2012Publication date: December 20, 2012Inventors: RONALD D. SHAW, LEE A. SHAW

Publication number: 20120301351Abstract: A high etch cleaner for aluminum and aluminum alloy substrates that leads to enhanced corrosion protective performance of a variety of anti-corrosion pretreatments. The cleaner comprises low levels of silicate of from 0 to 250 ppm, 50 to 500 ppm of at least one chelator, and has a pH of from 11.0 to 13.5. The cleaner may be used to etch from 0.5 to 4.0 grams per meter squared from substrates. Substrates treated with the cleaner and then coated with a variety of anti-corrosion pretreatments and outer coatings show enhanced corrosion resistance compared to substrates cleaned with standard cleaners that have low etch rates, high silicate levels and no chelating agents followed by anti-corrosion pretreatments and outer coatings.Type: ApplicationFiled: June 25, 2012Publication date: November 29, 2012Applicant: Henkel AF & Co.
